Unprecedented Data Samples for Jet Analysis: Closing the Gap

The project aims to analyze huge data samples from various areas like J/, W, b mesons, photons, and explore diffractive top and glueballs for physics breakthroughs. Urgent need for software development to process data after shutdown. Goals for 2003 include integrating Phase I data taking, Phase II funding, and producing preliminary physics results. Steps needed for physics include commissioning AFE’s, aligning FPD, and improving halo understanding. Pressure to justify bandwidth usage as luminosity increases.

  2. Unprecedented Data Samples Gap studies barely started on jet + Z analysis (Tamsin) Huge data samples on tape in these and other areas: J/, W, b, photon How about diffractive top? Glueballs? What are we waiting for???? Added bonus: It turns out that last several months data has working dipole detector (Mike) After shutdown: Full FPD Need your help to get physics results out!!!

  3. Alas: Missing Software (as of Beaune) • FPD_Reco Integration: D0Reco • Trigger Simulator: Raw Data • Forward Vertexing: L3 & Offline • L3 Geometry: Offline • DST & TMB Info: D0reco • FPD_Analyze: Offline (DST+TMB) • Alignment Tool (offline): Elastic stream • Calibration Tool (offline): LMB + Data • L2 Gap Tool

  4. Incomplete Software • L3 Single Interaction Tools • FPD Examine • Automatic Pot Motion Software • Event Display • Database • FPD analysis • Gap analysis • …

  5. Goals for 2003 (from Feb.) • Data taking with integrated Phase I • Add FPD triggers to global list • Complete funding and implementation of Phase II • Preliminary results on several physics topics • Would like to produce a detailed list in all areas: detector, software, PID, physics

  6. Steps Needed for Physics • Partial list of steps needed to get to physics • quality data: • Commission AFE’s • Include trigger scintillator information/ • basic and/or terms • Alignment of FPD • FPD database • Activate FPD_Reco • Halo understanding, reduction, and rejection • FPD info in DST’s and Thumbnails

  7. Pressure to Produce • Need results to justify use of bandwidth • Luminosity is going up (along with halo) • FPD window is limited (quadrupoles out in 2006) • New orbits at some point may lower acceptance • Many new CDF results
